After some use, even from a developer point of view, those options are  
really nice since you don't need to have RENDER x HWACCEL build trees.  
This saves compilation time of my poor system. Thanks. ;-)

BTW, it's worth mentioning a remaining problem with --hwaccel vaapi.  
Some UI elements don't overlay correctly. e.g. pause/unpause a video  
with JW's player. The VA-API part is correctly implemented with VA  
subpictures. The problem is in the AGG part. Either my  
renderEmptyVideo() is wrong, or AGG doesn't get it right. In theory, I  
just want AGG to generate whatever RGBA pixel making sure the alpha  
component is zero. AGG decides otherwise and generates me a fully  
opaque pixel (0xff alpha and low R/G/B components, 0x11 or 0x08 IIRC).  
If someone has an idea...

Thanks,
Gwenole.
